SYSTEM AND METHOD FOR THE AUTOMATION OF COLUMN AND MEDIA PACKING - This invention provides for the fully automated, hands free, packing of chromatography columns by means of delivering a pre-calculated volume of slurry and using two different packing modalities to stop the packing when either 1) this volume has been delivered in the column, or 2) when the adapter is moved to reach a bed height corresponding to the pre-calculated volume. Thus, a chromatography column can be packed in a fully automated fashion and such a column is 1) stable and 2) has the desired performance characteristic.

Animal Pad Bed Cover Extension - A bedcovering with an expandable center extension of fabric for accommodating an animal pet while sleeping. The bedcovering accommodates a pet, such as a dog, in sleeping on the bed without depriving human occupants of bed coverings. The bedcovering is comprised of two side panels affixed longitudinally to a central panel extension. Further, on each side panel, proximal to the center panel extension is a longitudinal attachment means. The two attachment means mate together to allow the center extension to be collapsed and hidden beneath the two side panels, giving the appearance of a standard bed covering. Non-pet owners who desire extended bed coverings may also use the present invention.

Tapered Channel Macro/Micro Feature for Mechanical Face Seals - A mechanical face seal includes a pair of relatively rotatable seal rings having opposing seal faces which define a sealing region therebetween. The sealing region extends radially between the inside and outside diameters of the seal rings to seal a fluid in a sealing chamber near one diameter thereof. The seal faces are provided with tapered channel macro/micro features which generate hydrodynamic lift during relative rotation of the seal rings. The tapered channel macro/micro feature shows significant improvement in seal performance when compared to an untextured face. Low contact and hence low wear are attributed to a more distributed hydrodynamic load support function. Likewise, low leakage is believed to be the result of optimized cavitation function, and no debris was discovered in the micro-features at the conclusion of any testing.

Abeyance Seal for High Temperature, High Pressure Applications - An abeyance seal includes a polymer actuation ring, which defines a flexible sealing lip normally spaced from the shaft. When subjected to leakage, this element collapses against the shaft and forms an initial sealing. Secondarily, a metal sealing/anti-extrusion ring provides a second seal during leakage. The polymer ring provides the initial sealing function during leakage at low differential pressure, and once the polymer ring seals to the shaft, increased sealed pressure loads the polymer ring against the metal sealing/anti-extrusion ring causing it to deform so that the metal ring comes into contact with the shaft to form a second seal.

SYSTEM AND METHOD OF ACCELERATING RESPONSE TIME TO INQUIRIES REGARDING INVENTORY INFORMATION IN A NETWORK - A method and system for distributing access to inventory items available at vendor locations includes user stations transmitting user inquiries on a communications network. Network-connected location servers access a set of inventory availability information associated with inventory items available at their respective location, for example, tables at a restaurant. The host server receives user inquiries regarding availability of items associated with at least some of the location servers and queries a cache server that locally stores a binary subset of the information from the location servers to determine if the requested item is available without having to separately query the database at each location. Particularly, a web server receives and stores information regarding only whether a requested item is available or not available from a particular location rather than how many items are available at the location. A user, therefore, can access availability of inventory items with less communications traffic.
